NSSecureCoding support

[Juan2662]

Hi guys, I notice that some chunks in the code in iOS (like FirebaseMessaging) is using NSCoding protocol
Can we have support for NSSecureCoding?

firebase-ios-sdk/FirebaseMessaging/Sources/Token/FIRMessagingTokenInfo.h

Line 28 in aec227b

@interface FIRMessagingTokenInfo : NSObject <NSCoding>

@Juan2662 Thanks for raising this. We've been incrementally adding NSSecureCoding support across Firebase and happy to review PR to help us accelerate.

Thanks for your answer @paulb777
When can we have full support for NSSecureCoding?
